[BUG] asymmetric model inference ignores `ModelResultFilter`

[br3no]

What is the bug?
There is a small bug in the TextEmbeddingModel class in relation with the new asymmetric model support. In the method addPrefixesToData, that is only called when an asymmetric model is used, I forgot to add the existing result filter to the new instance of the TextDocsInputDataSet that is created with the corresponding prefixes.

I noticed the issue while working on opensearch-project/neural-search#710.

How can one reproduce the bug?
Steps to reproduce the behavior:

1. run inference on an asymmetric model using a result filter
2. see that the result filter will not be applied

What is the expected behavior?
The result filter should be applied.

What is your host/environment?

N.a.

Do you have any additional context?
